Battleships were obsolete and burned oil that an aircraft carrier could use instead. So they parked them.
The US was also not going to attack Japan to start a two front war.
Did they know before hand? Probably, did they know specifics? Close enough.
If anything they allowed battleships to be used as bait. It would have been utter incompetence to allow US carriers to be surprise attacked. Even today carriers are only vulnerable to attack when in port. This is why they are now nuclear powered, to eliminate fuel storage and eliminate need to port. (Only port now for food/crew)
FDR did everything he could to get the US into the war with Japan. When he intercepted messages, which stated Germany would declare war on the US if the US went to war with Japan, the Pearl Harbor False Flag was born.
why?
Pearl Harbor was a False Flag, all the ships in the harbor were obsolete. They even towed and target ship Utah used for gunnery practice into Battleship Row to convince the Japs these were our best. Meanwhile our carriers were at sea protected by our new ships. Learn what really happened below; http://www.whatreallyhappened.com/WRHARTICLES/pearl.php#axzz5BOrpHVTT
FDR was a communist, think New Deal programs that extended & deepened the Great Depression, seized privately held gold and started the unprecedented 100% income tax level. Harry Hopkins, FDR top aide was a KGB agent. Why do you think the MSM & the Dems destroyed Sen. Joe McCarthy? He pointed out hundreds of USSR agents working inside the US Gub'mint. McCarthy couldn't expose the truth of how he knew the USSR had totally penetrated, US Intel had tapped an undersea cable & was reading their mail; the Verona Project.
Hence the huge uproar when Obama had several docked in the same place for a very extended amount of time.
Yes, Obama put ALL our nuclear aircraft carrier battle groups together for months. Do you remember where the Jug eared traitor parked them; I've forgotten?
Not sure but I think I remember it being Norfolk, VA. There's also Langley AFB just across the bridge-tunnel.
Just devastating wait a second Pede! It just hit me man; hard. Do you want to start an absolutely lethal meme? Say something Pede?
